Hello, thanks for the tips, one of the possible optimizations I also considered is on the etching process placing a heater to give temperatures of 50ºC, making the etching more efficient and capable of dissolving higher amount of copper making the same etching liquid last longer. But really right now I don't have much time to dedicate to this, so each person does their own personal improvements and the best one can do, the improvements I showed were the ones I made.
About my heat gun, I think you can control the temperature pretty well, the gun has a display that shows the temperature reading, so it's easy to control it.
And about my abilities to write in English, possibly it could be better, well when I have time, I'm going to read again the web site and correct the mistakes and bad sentence constructions that the text may have. I also use the Google translator to help me in some parts!!
, but it's hard using Google to translate, sometimes it translates the sentences in some crazy weird ways.
Thanks for viewing the website.
